Thanks.  I think I made all the changes needed for the MSVC 32-bit
build.  You can try the latest bzr trunk, the changes are in revision
106533.  The next pretest of Emacs 24 is expected to be available
tomorrow, so if you can try building that and reporting back, that'd
be swell.

I'm leaving this bug open for now, in case I goofed and it still
doesn't build.

Please note that only some of the _WIN64 changes are committed.  I
didn't want to rock the boat too much during the pretest, and also I
really feel that we've exceeded the amount of changes we can accept
without legal papers.  (I'd really encourage you to sign papers at
some point, to make all this line-counting business unnecessary.)  And
I understand that you don't have a fully functional 64-bit version
anyway.  So I only committed those _WIN64 related changes that fix
what we already had in the repository.  The rest will have to wait for
after the release of Emacs 24.1.

Thank you for your help so far.
